RAILWAY-oAR-TRUCK AR-RANGEMENT.

. Patented Sept.' 13, 19211 Application filed April 25V, 1921. SerialNo. 464,112.

1 To all y'zc/lam it may concern.'

Be it known that I. JOHN A. LaiIoN'r, a citizenof the Unit-ed States,residing at Chicago, in the county of Cool( and State of Illinois,l haveinvented certain new and` useful Improvements in Railway Car- TruckArrangements, of which the following` is a specification.

This invention relates to a railway 'ai' truck arrangement and moreparticularly to six-wheel equalizing trucks and is an improvement on thearrangement disclosed in my copending application Serial Xo. 33,416filed December 2. 1920.

@ne object of the invention is to further simplify and improveequalizing arrange ments for railway car trucks and especially those ofthe sixwheel type. l

Another object is to simplify the arrangement whereby Vthe loads aretransmitted from equalizing levers to the associated joui'- nal box in amanner to provide increased clearance at the intermediate journal box toaccommodate longitudinal movement of the equalizing mechanism includingthe equalizing' levers.

These and other objects are accomplished by means of the arrangementdisclosed on the accompanying sheet ofY drawings in which- Figure 1 is afragmentary vertical longitudinal sectional view through the side frameand associated parts of a six-wheel truck embodying my invention;

Fig. 2 is a fragmentary horizontal longitudinal sectional view taken inthe plane of ,line 2 2 of Fig. l; and

Fig. 3 is a transverse vertical sectional view taken in the planes ofthe irregular line 3-3 of Fig. l. Y

rThe various novel features of niy invention will be apparent from thefollowingl description and dra-wings and will be pai'- ticularly pointedoutin the appended claims.

Referring to the figures of the drawings, it will be noted that I havedisclosed my invention in connection with a railway car truck of thesix-wheel type and including a truck side frame 10 having end pockets(not shown) for the reception of end journal boxes and an intermedia-tepocket 11 for the reception of a middle journal box l2. This journal boxhas a main box portion for the reception of a journal 13 and outwardlycxtending: openended hollow wingsfat. each side thereof and eachincliuling side 'walls ld, whichvat theirouter ends are connected bv endwalls 15 which engage either the side" walls 16 which cooperate to formthe inter-v mediate journal box pocket 1l or engage the steel wearplates -17 secured thereto for guiding the journal box 12 in Vitsrelative vertical movements.

Y The main Vcentral body portion of the journal box l 12 is providedwith an inte- `rally fol-ined top or cover 18 upon which are directlymounted coil springsl and 22 'which are concentrically arranged withrespect to each other. the coil springs 21 being within the coil springs22 and heilig mounted over integrally formed upstanding .projections 23on the top 18 of the joui'i'ial box for the purpose of holdingthesprings in place.l `Cooperating to perform this function'. the toplS ofthe journalbox 12 is provided also with a central rib 2st`whicli hasalcurved contour conforming' fto the curve of the `coil springs'.,h/iounted .on top of these springs and bridging the sets of same isfavspiing cap25 in which arervertically slidably mounted two yplungers'or auxiliary spring caps 26, the `lower portions of which beardirectlyup'on the inner relatively light coil sprinGs 2l and the stemsof which are engagediby the lower surface of an equalizing beam 27,having a pivotal rocker projection 2S which is received within a pivotpocket 29 formed in the middle' in the equalizing beam 27. and clampingplate 30 and therefore the upper part of the cable 31 take a sinuouspath for the purpose of preventing the cable from slipping. Preferablythe clamping bolts 32 are located at the crimped portions of the cableand over the middle of the springs. The depending portions of the cable31 terminate in members 322L which receive the inner ends of equalizinglevers 33, which receive their llO loads from transverse bolstermembers, as disclosed in my copending application, ,Serial No. 133,417iled December 27, 1920. rllhe loads which are transmitted through theequalizing levers 33 are further transmitted through the cable 31,equalizing beam 27, main spring cap 25, auxiliary spring caps 26,springs 21 and 22, directly to the top 18 of the journal box 12. As aresult of the auxiliary spring caps or plungers 26 engaging the innerrelatively light coil springs 21 and also engaging the equalizing beam27, equalizing levers 33 are maintained in a horizontalk or givenposition with respect to the journal box and when the car is loaded, theinner coil springs are compressed and thus serve as auxiliary springs.It is apparent from Fig. 1 of the drawings that if the equalizing beam25 rotates in a counterclockwise direction, the auxiliary spring 21 onthe lei''t hand side will be compressed an increased amount, therebyincreasing the tendency of said spring to return the associatedequalizing lever 27 to a horizontal position it it has moved from suchposition.

rlChe equalizing beam has downwardly extending side langes 34, whichembrace the side of the main spring cap 25 for holding said parts intheir proper relative positions. The vertical passageways 35 formedbetween the journal box walls 14 and 15 are wide open at each end togive a considerable clearance for relatively wide range of longitudinalmovement for the equalizing le vers 33 which is occasioned duringstarting and stopping actions of the car.

It is my intention to cover all modifications of the invention fallingwithin the spirit and scope of the following claims.

I claim:

1. In a railway car truck, the combination of a journal box, springsmounted drectly on top of said journal box, a spring cap bridging Vsaidsprings, an equalizing beam, said cap yand beam having a connectionwhereby one may be rotated' onthe other, and means operatively connectedto said equalizing beam whereby loads may be transmitted to the latterand equalized with respect to said journal box.

2. In a railway car truck, the combination of a journal box, resilientmeans mounted directly on top of same, a member supported on saidresilient means, an equalizing beam, said member and beam having aconnection whereby one may be rotated on thel other, and meansoperatively associated with said beam whereby loads may be transmittedto the latter and equalized with respect to said journal box.

3. In a railway car truck, the combination olf a journal box having amain body portion and outwardly extending` hollow wings, load carryingsprings mounted directly on top of said journal box, and equalizingmechanism operatively associated with said springs and including partsextending through said hollow wings.

1. In a railway car truck, the combination olf a journal box, equalizingmechanism operatively connected thereto and including an equalii/Jingbeam mounted over said'box, and a load transmitting cable secured tosaid equalizing beam in a sinuous path to prevent slipping of saidcable.
